Rewards will be "doubled" in next days!perfect time to buy now with this cheap price,it will go to the moon,now block 20k and will be doubled at 28k soon.
I checked the OP to see what you mean. It is certainly good for Ultranatum masternode owners. However, it is a little bit strange, rewards increased over time, not decrease as usual.
I also know that if total active masternode increase (double) in the same period, then the double rewards per block for masternodes will only keep the rewards for MN owners stable, which don't let them go, and in turn help to maintain the sustainability of the network, generally.
I guess this is the idea behind the scenes.
